4 Motor Starter Protectors/Circuit Breakers SIRIUS 3RV2 Motor Starter Protectors/Circuit Breakers up to 40 A 3RV29 infeed system Overview The 3RV29 infeed system is a convenient means of energy supply and distribution for a group of several motor starter protectors or complete load feeders with a screw or spring-type connection in sizes S00 and S0 (exception: this system cannot be used for the 3RV21, 3RV2 and 3RV28 motor starter protectors/circuit breakers). The system is based on a basic module complete with a lateral incoming unit (three-phase busbar with infeed). This infeed with spring-type terminals is mounted on the right or left depending on the version and can be supplied with a maximum conductor cross-section of 25 mm 2 (with end sleeve). A basic module has two sockets onto each of which a motor starter protector can be snapped. Expansion modules are available for extending the system (three-phase busbars for system expansion). The individual modules are connected through an expansion plug. The electrical connection between the three-phase busbars and the motor starter protectors is implemented through plug-in connectors. The complete system can be mounted on a TH 35 standard mounting rail to IEC 6015 and can be expanded as required up to a maximum current carrying capacity of 63 A. The system is mounted extremely quickly and easily thanks to the simple plug-in technique. Thanks to the lateral infeed, the system also saves space in the control cabinet. The additional overall height required for the infeed unit is only 30 mm. The alternative infeed possibilities on each side offer a high degree of flexibility for configuring the control cabinet: Infeed on left-hand or right-hand side as well as infeed on one side and outfeed on the other side to supply further loads are all possible. A terminal block with spring-type connections in combination with a standard mounting rail enables the integration of not only SIRIUS motor starter protectors but also single-phase, 2-phase and 3-phase components such as 5SY miniature circuit breakers or SIRIUS relay components. The 3RV29 infeed system is approved in accordance with IEC to 500 V. It is also UL-approved and authorized for "Self-Protected Combination Motor Controller" (Type E starter) as well as for Type F starter (Type E starter + contactor). 3b 5 5 3a NSB0_ a 3-phase busbar with infeed 3-phase busbar for system expansion Expansion plug b Extra-wide expansion plug End cover Plug-in connector Contactor base Terminal block SIRIUS 3RV29 infeed systems /40 Siemens IC

5 Motor Starter Protectors/Circuit Breakers SIRIUS 3RV2 Motor Starter Protectors/Circuit Breakers up to 40 A 3RV29 infeed system $ Three-phase busbars with infeed A three-phase busbar with infeed unit is required for connecting the incoming supply. These modules comprise one infeed module and two sockets which each accept one motor starter protector. A choice of two versions with infeed on the left or right is available. The infeed is connected to spring-type terminals. They permit an infeed with conductor cross-sections of up to 25 mm 2 with end sleeves. An end cover is supplied with each module. % Three-phase busbars for system expansion The three-phase busbars for system expansion support expansion of the system. There is a choice of modules with two or three sockets. The system can be expanded as required up to a maximum current carrying capacity of 63 A. An expansion plug is supplied with each module. &a Expansion plug The expansion plug is used for electrical connection of adjacent three-phase busbars. The current carrying capacity of this plug equals 63 A. One expansion plug is supplied with each threephase busbar for system expansion. Additional expansion plugs are therefore only required as spare parts. &b Extra-wide expansion plug The wide expansion plug makes the electrical connection between two three-phase busbars, thus performing the same function as the 3RV291-5BA00 expansion plug; the electrical characteristics (e.g. a current carrying capacity of 63 A) are identical. The 3RV291-5E expansion plug is 10 mm wider than the 3RV291-5BA00 expansion plug, hence in the plugged state there is a distance of 10 mm between the connected threephase busbars. This distance can be used to lay the auxiliary current and control current wiring ("wiring duct"). The motor starter protector and contactor can be wired from underneath, which means that the complete cable duct above the system can be omitted. ( End cover The end cover is used to cover the three-phase busbar at the open end of the system. This cover is therefore only required once for each system. An end cover is supplied with each three-phase busbar system with infeed. Further end covers are therefore only required as spare parts. * Contactor base Load feeders can be assembled in the system using the S00 and S0 contactor base. The contactor bases are suitable for contactors sizes S00 and S0 with spring-type and screw terminals and are simply snapped onto the three-phase busbars. Direct-on-line starters and reversing starters are possible. One contactor base is required for direct-on-line starters and two are required for reversing starters. To assemble load feeders for reversing starters, the contactor bases can be arranged alongside each other (90 mm overall width). In this case the mechanical interlocking of the contactors is possible. The S0 contactor bases are also suitable for soft starters size S00 and S0 with screw terminal. The infeed system is designed for mounting onto a TH 35 standard mounting rail with.5 mm overall depth. This standard mounting rail gives the contactor base a stable mounting surface to sit on. If standard mounting rails with a depth of 15 mm are used, the spacer connected to the bottom of the contactor base must be knocked out and plugged into the mating piece that is also on the underside. Then the contactor base also has a stable mounting surface. When standard mounting rails with a depth of.5 mm are used, the spacer has no function and can be removed. The link modules are used for direct start load feeders, in which case the use of a contactor base is not absolutely necessary. Motor starter protector and contactor assemblies can then be directly snapped onto the sockets of the three-phase busbars. For feeders of sizes S00 and S0, the corresponding 3RA , 3RA , 3RA or 3RA link modules should generally be used. + Terminal block The 3RV291-5D terminal block enables the integration of not only SIRIUS motor starter protectors but also single-phase, 2-phase and 3-phase components. The three phases can be fed out of the system using the terminal block; which means that single-phase loads can also be integrated in the system. The terminal block is plugged into the slot of the expansion plug and thus enables outfeeding from the middle or end of the infeed system. The terminal block can be rotated through 180 and be locked to the support modules of the infeed system. In addition, the 45 mm wide TH 35 3RV191-B standard mounting rail option for screwing onto the support plate facilitates plugging the single-phase, two-phase and three-phase components onto the infeed system. ) Plug-in connector The plug-in connector is used for the electrical connection between the three-phase busbar and the 3RV2 motor starter protector. These plug-in connectors are available for screw or spring-type terminals. Siemens IC /41

For your orders, please use the article numbers quoted in the catalog in the Selection and ordering data. Application Operating conditions 3RV1 motor starter protectors/circuit breakers are suitable for use in any climate. They are intended for use in enclosed rooms in which no severe operating conditions (such as dust, caustic vapors, hazardous gases) prevail. When installed in dusty and damp areas, suitable enclosures must be provided. 3RV1 motor starter protectors/circuit breakers can optionally be fed from the top or from below. The permissible ambient temperatures, the maximum switching capacities, the tripping currents and other boundary conditions can be found in the technical specifications and tripping characteristics, see Reference Manual "Protection Equipment Circuit Breakers Molded Case Circuit Breakers", 3RV1 motor starter protectors/circuit breakers are suitable for operation in IT systems (IT networks). In this case, the different short-circuit breaking capacity in the IT system must be taken into account, see page /4. Since operational currents, starting currents and current peaks are different even for motors with identical power ratings due to the inrush current, the motor ratings in the selection tables are only guide values. The specific rated and start-up data of the motor to be protected is always paramount to the choice of the most suitable motor starter protector/circuit breaker. This also applies to motor starter protectors for transformer protection. Possible uses The 3RV1 motor starter protectors/circuit breakers can be used: For short-circuit protection For motor protection (also with overload relay function) For system protection For short-circuit protection for starter combinations For transformer protection As main and EMERGENCY-STOP switches For fuse monitoring For operation in IT systems (IT networks) For switching of DC currents As voltage transformer circuit breakers In areas subject to explosion hazard (ATEX) Approved as circuit breakers according to UL 489 (3RV142) For more details see Reference Manual "Protection Equipment Circuit Breakers Molded Case Circuit Breakers" Siemens IC /45

The isolator module covers the terminal screws of the transverse auxiliary switch. If the isolator module is used, we therefore recommend that either the lateral auxiliary switches be fitted or that the isolator module not be mounted until the auxiliary switch has been wired. An auxiliary switch block can be inserted transversely on the front. The overall width of the motor starter protectors remains unchanged. One of the three lateral auxiliary switches can be mounted on the left side per motor starter protector/circuit breaker. The contacts of the auxiliary switch close and open together with the main contacts of the motor starter protector/circuit breaker. The width of the lateral auxiliary switch with two contacts is 9 mm. One lateral auxiliary switch with four contacts can be mounted on the left side per motor starter protector/circuit breaker. The contacts of the auxiliary switch close and open together with the main contacts of the motor starter protector/circuit breaker. The width of the lateral auxiliary switch with four contacts is 18 mm. One signaling switch can be mounted on the left side of each motor starter protector. The signaling switch has two contact systems. One contact system always signals tripping irrespective of whether this was caused by a short circuit, an overload or an auxiliary release. The other contact system only switches in the event of a short circuit. There is no signaling as a result of switching off with the handle. In order to be able to switch on the motor starter protector again after a short circuit, the signaling switch must be reset manually after the error cause has been eliminated. The overall width of the signaling switch is 18 mm. For remote-controlled tripping of the motor starter protector/circuit breaker. The release coil should only be energized for short periods (see circuit diagrams). Trips the motor starter protector/circuit breaker when the voltage is interrupted and prevents the motor from being restarted accidentally when the voltage is restored. Used for remote-controlled tripping of the motor starter protector/circuit breaker. Particularly suitable for EMERGENCY-STOP disconnection by way of corresponding EMERGENCY-STOP pushbuttons according to DIN EN Function and use as for the undervoltage release without leading auxiliary contacts, but with the following additional function: the auxiliary contacts will open in switch position OFF to deenergize the coil of the undervoltage release, thus interrupting energy consumption. In the "tripped" position, these auxiliary contacts are not guaranteed to open. The leading contacts permit the motor starter protector/circuit breaker to reclose. The overall width of the auxiliary release is 18 mm. Isolator modules can be mounted to the upper terminal end of the size S2 motor starter protectors. The supply cable is connected to the motor starter protector through the isolator module. The plug can only be unplugged when the motor starter protector is open and isolates all 3 poles of the motor starter protector from the network. The shock-protected isolation point is clearly visible and secured with a padlock to prevent reinsertion of the plug.

31 Motor Starter Protectors/Circuit Breakers SIRIUS 3RV1 Motor Starter Protectors/Circuit Breakers up to 100 A Accessories Rotary operating mechanisms Overview Door-coupling rotary operating mechanisms Motor starter protectors/circuit breakers with a rotary operating mechanism can be mounted in a control cabinet and operated externally by means of a door-coupling rotary operating mechanism. When the cabinet door with motor starter protector/circuit breaker is closed, the operating mechanism is coupled. When the motor starter protector/circuit breaker closes, the coupling is locked which prevents the door from being opened unintentionally. This interlock can be defeated by the maintenance personnel. In the OPEN position, the rotary operating mechanism can be secured against reclosing with up to three padlocks. Inadvertent opening of the door is not possible in this case either. SIRIUS 3RV1926-0K door-coupling rotary operating mechanism NSB0_0108 NSB0_0109a Remote motorized operating mechanisms 3RV1 motor starter protectors/circuit breakers are manually operated controls. They automatically trip in case of an overload or short circuit. Intentional remote-controlled tripping is possible by means of a shunt release or an undervoltage release. Reclosing is only possible directly at the motor starter protector/circuit breaker. The remote motorized operating mechanism allows the motor starter protectors/circuit breakers to be opened and closed by electrical commands. This enables a load or an installation to be isolated from the network or reconnected to it from an operator panel. If the motor starter protector/circuit breaker is tripped as a result of overload or short circuit, it will be in tripped position. For reclosing, the remote motorized operating mechanism must first be set manually or electrically to the 0 position (electrically by means of the Open command). Then it can be reclosed. The remote motorized operating mechanism is available for motor starter protectors/circuit breakers of size S2 (I n max = 50 A) and S3 (I n max = 100 A) that are designed for control voltages of 230 V AC and 24 V DC. The motor starter protector/circuit breaker is fitted into the remote motorized operating mechanism as shown in the drawing. In the "MANUAL" position, the motor starter protector/circuit breaker in the remote motorized operating mechanism can continue to be switched manually on site. In the "AUTOMATIC" position, the motor starter protector/circuit breaker is switched by means of electrical commands. The switching command must be applied for a minimum of 100 ms. The remote motorized operating mechanism closes the motor starter protector/circuit breaker after a maximum of 1 s. On voltage failure during the switching operation it is ensured that the motor starter protector/circuit breaker remains in the "OPEN" or "CLOSED" position. In the "MANUAL" and "OFF" position, the remote motorized operating mechanism can be locked with a padlock. RESET function The RESET button on the motorized operating mechanism serves to reset any 3RV1921-1M signaling switch that might be installed.

38 Motor Starter Protectors/Circuit Breakers SIRIUS 3RV1 Molded Case Motor Starter Protectors up to 800 A General data Benefits High short-circuit breaking capacity in the feeder Optimum usability in motor feeders for the special voltages 440 V, 480 V, 550 V and 690 V Compact design The releases are available both in purely magnetic (up to 32 A) and in solid-state versions (100 A to 800 A). Available for motor or starter protection (short-circuit protection alone) Application Operating conditions The 3RV1 molded case motor starter protectors for up to 800 A can be operated at ambient temperatures between -25 C and +0 C. They can be used according to IEC in the most difficult environmental conditions with a hot and damp climate. Since operational currents, starting currents and current peaks are different even for motors with identical power ratings due to the inrush current, the motor ratings in the selection tables are only guide values. The specific rated and start-up data of the motor to be protected is always paramount to the choice of the most suitable molded case motor starter protectors. The 3RV1 molded case motor starter protectors up to 800 A have not been tested for use with frequency converters. The possibility of premature tripping in such applications cannot therefore be ruled out. Possible uses The 3RV1 molded case motor starter protectors for up to 800 A are suitable as switching and protection devices for motors. The following versions are available: For motor protection; the overload and short-circuit releases are designed for optimized protection and direct-on-line starting of induction squirrel-cage motors. The motor starter protectors have an electronic release which not only provides short-circuit and overload protection but is also sensitive to phase failure and phase unbalance and offers protection in the event of rotor blockage. For starter combinations; these molded case motor starter protectors are used for short-circuit protection in combinations of circuit breaker, motor contactor and overload relay. They are equipped with a purely magnetic release (up to 32 A) or a solid-state release (100 A to 800 A). Standards and specifications The electronic releases for motor protection comply with IEC Isolating features are also compliant with IEC The 3RV1 molded case motor starter protectors comply in addition with IEC (shock and vibration strength) and are certified for the specifications of the most important marine classification societies: RINA Det Norske Veritas Bureau Veritas Lloyds Register of Shipping Germanischer Lloyd American Bureau of Shipping /4 Siemens IC

The overload relay can be connected directly to the contactor using these pins. Stand-alone installation is possible as an alternative (in conjunction with a terminal bracket for stand-alone installation). Selector switch for manual/automatic RESET and RESET button: With this switch you can choose between manual and automatic RESET. A device set to manual RESET can be reset locally by pressing the RESET button. A remote RESET is possible using the RESET modules (accessories), which are independent of size. Switch position indicator and TEST function of the wiring: Indicates a trip and enables the wiring test. Motor current setting: Setting the device to the rated motor current is easy with the large rotary knob. STOP button: If the STOP button is pressed, the NC contact is opened. This switches off the contactor downstream. The NC contact is closed again when the button is released. Connecting terminals: Depending on the device version, the connecting terminals for screw, spring-type or ring terminal lug connection are configured for the main and auxiliary circuit. A sealable transparent cover can be optionally mounted (accessory). It secures the motor current setting against adjustment. SIRIUS 3RU2126-4FB0 thermal overload relay The 3RU21 thermal overload relays up to 40 A have been designed for inverse-time delayed protection of loads with normal starting (for "Function" see manual "SIRIUS Innovations SIRIUS 3RU2/3RB3 Overload Relays", against excessive temperature rises due to overload or phase failure. An overload or phase failure results in an increase of the motor current beyond the set rated motor current. Via heating elements, this current rise heats up the bimetal strips inside the device which then bend and as a result trigger the auxiliary contacts by means of a tripping mechanism. The auxiliary contacts then switch off the load by means of a contactor. The break time depends on the ratio between the tripping current and current setting I e and is stored in the form of a long-term stable tripping characteristic (see "Characteristic Curves" The "tripped" status is signaled by means of a switch position indicator. Resetting takes place either manually or automatically after a recovery time has elapsed (for "Function" see manual "SIRIUS Innovations SIRIUS 3RU2/3RB3 Overload Relays", The 3RU2 thermal overload relays are suitable for operation with frequency converters. Please follow the instructions in the manual "SIRIUS Innovations 3RU2/3RB3 Overload Relays", see The devices are manufactured in accordance with environmental guidelines and contain environmentally friendly and reusable materials.

54 Overload Relays SIRIUS 3RU2 Thermal Overload Relays 3RU2 up to 40 A for standard applications Benefits The most important features and benefits of the 3RU21 thermal overload relays are listed in the overview table (see "General Data", page /82 onwards). Application Industries The 3RU21 thermal overload relays are suitable for customers from all industries who want to guarantee optimum inverse-time delayed protection of their electrical loads (e.g. motors) under normal starting conditions (CLASS 10). Application The 3RU21 thermal overload relays have been designed for the protection of three-phase and single-phase AC and DC motors. If single-phase AC or DC loads are to be protected by the 3RU21 thermal overload relays, all three bimetal strips must be heated. For this purpose, all main current paths of the relay must be connected in series. Ambient conditions The 3RU21 thermal overload relays have temperature compensation according to IEC for the temperature range of -40 to +60 C. For temperatures from +60 to +0 C, the upper set value of the setting range must be reduced by the factor listed in the table below.
